[CORD-46] Create a broadcast group for each subnet
DONE
- Expose subnet-to-ports information from DeviceProperties and DeviceConfiguration
- Create subnetNextObjectiveStore to store <DeviceId, IpPrefix> to nextId mapping
- Implement broadcast NextObjective in SpringOpenTTP
Use ALL group type to achieve broadcast
TODO (not in this submission)
- Push ARP table for a host when its location is learned
- Push default ARP table miss rule. Action = to the broadcast group
